Refer to the exhibit.

A junior network administrator was given the task of configuring port security on SwitchA to
allow only PC_A to access the switched network through port fa0/1. If any other device is
detected, the port is to drop frames from this device. The administrator configured the
interface and tested it with successful pings from PC_A to RouterA, and then observes the
output from these two show commands.
Which two of these changes are necessary for SwitchA to meet the requirements? (Choose
two.)

A.
Port security needs to be globally enabled.

B.
Port security needs to be enabled on the interface.

C.
Port security needs to be configured to shut down the interface in the event of a violation.

D.
Port security needs to be configured to allow only one learned MAC address.

E.
Port security interface counters need to be cleared before using the show command.

F.
The port security configuration needs to be saved to NVRAM before it can become active.

Explanation:
From the output we can see that port security is disabled so this needs to be enabled. Also,
the maximum number of devices is set to 2 so this needs to be just one if we want the single
host to have access and nothing else.
